Jackson said: "One again I think we're so blessed with really amazing talent and what I'm really impressed by - like last year - is there is such a variety.

"People who would never have auditioned for the show ever showed up and [we have] different types of musical styles."

Jackson added: "I think people have the misconception that this is just a pop show but we've got R&B, jazz, even some kids with some hip-hop flavor, and of course, we always have country. I just love the variety."
